Problem with Shadow Casters and DirectX

Scripting Issues
1

Hi!

When adding a DirectionalLight or SpotLight and setting it to be a shadow caster, I get an DX9 exception (works fine in OpenGL). If I don’t call setShadowCaster, the problem goes away. Am I missing some vital config value in the config file?

Greatful for any help!

BR // Astrogee

self.dlight = self.render.attachNewNode(DirectionalLight('dlight'))
self.dlight.node().setColor(VBase4(0.3, 0.3, 0.3, 0.5))
self.dlight.node().setShadowCaster(True)
self.dlight.node().getLens().setFilmSize( 50, 50 ); 
self.dlight.node().getLens().setNearFar( -10.0, 50.0 );
self.dlight.setHpr(45, -45, 0)
self.render.setLight(self.dlight)

Config file:

load-display pandadx9
win-origin 20 20
win-size 1280 800
fullscreen #f

Well if you want to use the shader generator, you should use OGL. Its not just the automated shadows that will give you problems…

I’m not dead set on using DX, I was just under the impression that Panda handles DX and OGL equally(almost). Anyway, I’ll stick to OGL then.

Thanks
